You have to love something like Serendipity

I can’t think why I really like this, but I do. I think it’s a lovely thing, but I really don’t know why. It doesn’t fit my ideas of utility at all. If you’ve no idea about what I’m talking about, then you should know that Serendipity is an app built on Spotify’s API which shows where two people are playing the same song at the same time anywhere in the world. It is quite amazing to watch, but, as far as I can tell it has no real purpose. Not that it needs it though.
